Question

is proline polar or non polar​

Answer 1

Answer:

Proline is not polar and basic because the N is not from the side chain. Proline originates from glutamic acid, the carboxy reduced to an aldehyde, amino group attacking to form the Schiff base, and further reduction. Basically, the N is from the original alpha-amino group. Proline qualifies as nonpolar and cyclic.
